A 20cm-long rod with a diameter of 0.250 cm is loaded with a 5000 N weight. If the diameter of the bar is 0.490 at this load, determine: I. the engineering stress and strain, and [2] II. the true stress and strain
If the diameter of the bar is 0.490 at this load, determine I. the engineering stress and strain, and [2] II. the true stress and strain is 1561. 84 MPa.
What is strain?Strain is a unitless degree of ways a great deal an item receives larger or smaller from an implemented load. Normal stress happens while the elongation of an item is in reaction to an everyday pressure (i.e. perpendicular to a surface), and is denoted via way of means of the Greek letter epsilon.

Answer:
Explanation:
The standard conversion factor for pounds and kg is 2.20462 pounds make 1 kg
This is a proportion question. A proportion consists of 2 equal ratios. If 3 of the 4 parts are known, the 4th part can be found.
Givens
1 kg = 2.20462 pounds (that's 2 of the 4 parts)
32kg = x 32 kg is our 3rd part.

Two sides and the included angle of triangle were measured as under
A = 757.64 +0.045 m
B = 946.70+ 0.055 m
C = 54°18+25"
Based on the calculations, the area of this triangle is equal to 290,136.87 m².
Given the following data:
Side A = 757.64 +0.045 m.Side B = 946.70+ 0.055 m.Angle, C = 54°18'25"How to calculate the area of this triangle?Mathematically, the area of a triangle can be calculated by using this formula:
Area = 1/2 × b × h
Where:
b is the base area.h is the height.In this scenario, the area of this triangle is given by:
Area = 1/2 × a × b × sinC
Substituting the given parameters into the formula, we have:
Area = 1/2 × 757.64 × 946.70 × sin(54°18'25")
Area = 580,273.74/2
Area = 290,136.87 m².
Next, we would determine the probable error of the area by using this formula:
[tex]PE_A = \pm k \sqrt{PE} \\\\PE_A = \pm \frac{1}{2} \times sinC \sqrt{(aPE_b)^2 + (bPE_a)^2 } \\\\PE_A = \pm \frac{1}{2} \times sin(54^{\circ}18'25") \times \sqrt{(757.64 \times 0.045)^2 + (946.70 \times 0.055)^2 } \\\\PE_A = \pm 0.4045 \times \sqrt{1,162.39 +2,711.12}\\\\PE_A = \pm 0.4045 \times \sqrt{3,873.51}\\\\PE_A = \pm 0.4045 \times 62.2375\\\\PE_A = \pm25.1751 \;m^2[/tex]
